• Performing a fuzzy search may retrieve terms with similar spellings: te sach y van cay phoi. hieu van cau ((tuc va) OR (thuc va)) danh vi ((cua triet) or (cua viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y van cay phoi. hieu van cau ((tuc va) OR (thuc va)) danh vi ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y van cay phoi. hieu van cau ((tuc va) OR (thuc va)) danh vi ((cua triet) or (cua viet))".
• Adding a wildcard symbol may retrieve word variants: te sach y van cay phoi. hieu van cau ((tuc va) OR (thuc va)) danh vi ((cua triet) or (cua viet))*.
